Canon 24EX, 14EX Automatic Flash in Each Shooting Mode, Aperture-priority AE, Manual exposure

Automatic Flash in Each Shooting Mode

Just set the camera’s shooting mode to <W> (aperture-priority AE) or <O> (manual exposure) to enable macro flash shooting with E-TTL II/ E-TTL autoflash.

<W> Aperture-priority AE

This mode is effective for controlling the depth of field or obtaining the standard exposure for both the subject and background. You set the aperture as desired, and the shutter speed is set automatically (30 sec.

-1/X* sec.) to obtain the standard background exposure. Based on the set aperture, E-TTL II/E-TTL autoflash is used for the shot.

Since a slow shutter speed will be used for low-light scenes, using a tripod is recommended.

If the shutter speed display blinks, it means that the background exposure will be underexposed or overexposed. Adjust the aperture until the shutter speed display stops blinking.

<O> Manual exposure

Select this mode when you want to set both the shutter speed and aperture manually. Standard exposure of the main subject is obtained with the flash. The exposure of the background is obtained with the shutter speed (buLb, 30 sec. - 1/X* sec.) and aperture combination you set.

With <X> (shutter-priority AE), you set the shutter speed (30 sec. - 1/X* sec.) as desired, and the camera sets the aperture automatically. However, this mode is not recommended since you cannot set the aperture.

In the <Z> or <Y> mode, the result will be the same as shooting in the <V> mode.

* 1/X sec. is the respective camera’s maximum flash sync speed.
